4K All-in-One Video Bar — NT-EC-VB-4K
4K UHD · 20MP · Integrated Camera/Mic/Speaker · AI Auto-Framing
Integrated all-in-one video bar combining a 4K ultra-high-definition camera, beamforming microphone array, and full-range speaker in a single device. The NT-EC-VB-4K features a 20-megapixel CMOS sensor delivering clear 4K video at 30fps with backward compatibility for 1080P and 720P. AI-powered technology automatically frames participants, detects faces and human shapes, and positions focus on speakers without manual intervention. POE cascade support allows up to 3 expansion microphones for extended room coverage. Wireless BYOM (Bring Your Own Meeting) connectivity enables seamless screen sharing from personal devices. Designed for small to medium-sized enterprise meeting spaces with flexible installation options.
